cmdlet

• A cmdlet is a lightweight command that is used in the PowerShell environment
• Commands for PowerShell are known as cmdlets. Cmdlets are native PowerShell commands. In addition to cmdlets, PowerShell allows you to run any command available on your system
• Cmdlets are collected into PowerShell modules that can be loaded on demand
• Cmdlets can be written in any compiled .NET language or in the PowerShell scripting language itself
• A cmdlet is a single command that participates in the pipeline semantics of PowerShell. This includes binary (C#) cmdlets, advanced script functions, CDXML, and Workflows.
• Cmdlets perform an action and typically return a Microsoft .NET object to the next command in the pipeline
• The PowerShell runtime invokes these cmdlets within the context of automation scripts that are provided at the command line (also invokes them programmatically through PowerShell APIs)

Pipeline

• Pipeline is a command chain in which output of one command goes to next command as input

• A pipeline is a series of commands connected by pipeline operators (

  ) (ASCII 124)

  • Each pipeline operator sends the results of the preceding command to the next command.
• The output of the first command can be sent for processing as input to the second command, and so on…
